System and Method for Power Management in an Electronic Device

1. A method of operating a television, comprising: collecting usage data for a plurality of device functions of the television by using a processor to monitor input source selection during operation of the television; comparing the collected usage data for each of the plurality of device functions; and reducing power consumption by circuitry associated with at least one of the plurality of device functions while the television is in use when comparing the collected usage data indicates that the at least one of the plurality of device functions is used less than at least another of the plurality of device functions.

2. The method of claim 1 , wherein the usage data comprises an amount of time each of the plurality of device functions is used by the user.

3. The method of claim 1 , wherein the usage data comprises a number of times each of the plurality of device functions is accessed by the user.

4. The method of claim 1 , wherein the usage data comprises a number of times that the television has been powered up.

5. The method of claim 1 , wherein power is removed from the circuitry associated with the at least one of the plurality of device functions when the television is in a particular mode of operation.

6. The method of claim 5 , wherein the particular mode of operation is an Energy Star Run Mode.

7. The method of claim 1 , wherein the circuitry associated with the at least one of the plurality of inputs comprises a signal tuner.

8. The method of claim 1 , wherein the plurality of device functions each comprises tuning an input signal from a different input source.

9. The method of claim 1 , wherein collecting usage data comprises electronically monitoring a video switching state machine.

10. The method of claim 1 , wherein the step of reducing power consumption is automatically repeated each time a required amount of the usage data is collected.

11. The method of claim 1 , wherein the step of reducing power consumption occurs after the expiration of a specified time.

12. The method of claim 1 , wherein the step of reducing power consumption occurs after a specified number of video switching events.

13. The method of claim 1 , wherein the step of reducing power consumption occurs after a specified number of times that the television is powered up.

14. A television that performs a plurality of device functions, the television comprising: circuitry associated with each of the plurality of device functions; and a processor that is adapted to collect usage data for each of the plurality of device functions via monitoring of input source selection during operation of the television, to compare the collected usage data for the plurality of device functions, and to reduce power consumption by circuitry associated with at least one of the plurality of device functions while the television is in use when comparison of the collected usage data indicates that the at least one of the plurality of device functions is used less than at least another of the plurality of device functions.

15. The television of claim 14 , wherein the circuitry associated with the at least one of the plurality of device functions comprises a signal tuner.

16. The television of claim 14 , wherein the circuitry associated with the at least one of the plurality of device functions comprises a digital signal tuner.

17. The television of claim 14 , wherein the plurality of device functions each comprises tuning an input signal from a different input source.

18. The device of claim 14 , further comprising a video switching state machine, wherein the processor is adapted to collect the usage data by monitoring the video switching state machine.

19. A television, comprising: means for collecting usage data for a plurality of device functions of the television by monitoring input source selection during operation of the television; and means for comparing the collected usage data and reducing power consumption by circuitry associated with at least one of the plurality of device functions while the television is in use when comparing the collected usage data indicates that the at least one of the plurality of device functions is used less than at least another of the plurality of device functions.
